Heat exchange apparatus () includes first heat transfer tubes (), contained within an enclosure () and coupled to receive a first fluid heated by an energy source (). Second heat transfer tubes () are interleaved with the first heat transfer tubes within the enclosure so as to heat a second fluid contained in the second heat transfer tubes by transfer of heat from the first fluid, and are coupled to output the heated second fluid to drive target equipment (). A heat storage medium () fills the enclosure.

Integrated thermal storage, heat exchange, and steam generation

A heat receiver tube for absorbing solar energy and for transferring the absorbed solar energy to a heat transfer fluid is provided. The heat receiver tube includes a first partial surface, which is covered by a solar energy absorptive coating, and a second partial surface, which is substantially uncovered by the absorbing coating. Also provided is a parabolic trough collector with a parabolic mirror having a sunlight reflecting surface for concentrating sunlight in a focal line of the parabolic minor and a heat receiver tube which is arranged in the focal line of the parabolic mirror, wherein the heat receiver tube is arranged in the focal line such that the first partial surface with the solar absorptive coating is at least partially located opposite to the sunlight reflecting surface and the second partial surface at least partially averted to the sunlight reflecting surface.

Heat receiver tube, method for manufacturing the heat receiver tube, parabolic trough collector with the receiver tube and use of the parabolic trough collector

A heat receiver tube having first, second, and further partial heat receiver tube surfaces for absorbing and transferring solar energy to heat transfer fluid is presented. The first and further partial heat receiver tube surfaces are formed by solar absorptive coatings deposited on partial surfaces of core tube. The second partial heat receiver tube surface is formed by emission radiation inhibiting coating deposited on second core tube surface for inhibiting emissivity for infrared radiation. The further partial heat receiver tube surface is arranged in radiation window of second partial heat receiver tube surface such that direct sunlight impinges further partial heat receiver tube surface. The heat receiver tube is arranged in focal line of parabolic mirror of parabolic trough collector. The first partial heat receiver tube surface and sunlight reflecting surface is arranged face to face, second and further partial heat receiver tube surfaces are averted to reflecting surface.

A getter support assembly for supporting getters in a focusing collector type solar collector system comprising a tube radiation absorber (TRA) and a glass enclosure tube, defining therebetween an annular space, and a solar radiation focusing reflector. The getter support assembly comprises a bridge formed with an elongated trough having a getter support portion. The bridge further comprising feet fixedly attached to the TRA supporting the trough so that the trough is spaced apart from the TRA. The trough further comprises a radiation reflecting surface facing the TRA for blocking radiation emitted from the TRA and missed solar radiation reflected from the reflector.
